Am i missing something here? From my understanding after a charge down everyone is played onside, so no problem there. And since when is kicking the ball forward (regardless of whether it came off his foot or heel) considered a knock on?

Really? What clip did you see? I couldn't see Roncero try and do anything to ROG, who should have been cited for kicking up at the Argentine. ROG is a good player but is one filthy cocky so and so, who i am more than happy to see get put on his arse time and time again.
